I am working on a coastal island supported largely by tourism, such as people vacationing there for the holidays and in the summer to enjoy the beach, or those looking to get to the beach a few hours drive from where they live as a quick weekend trip. I'd like some help shaping the island so it isn't super wide, and is shorter on both the far right and far left sides of it, has room in the middle for multiple streets, and looks a bit more like a realistic island. I'd also like some help making the island a little bit bigger in size. Can someone help me with this? I have ideas in mind for what will go on the island, which will probably be just a single town, but I first need help making a good island, which I have little experience in doing. I'm getting some inspiration for my island from the island where the town of Ocean Isle Beach in North Carolina, USA is, which is a place I've been to a few times over the years as I have some relatives who live not far from there.
The island is off the coast of the town of Newington, south of West Bay City in the country of Commonia.
